I've always liked older stuff, even when I was little kid. I preferred comics from the silver/golden age rather than current, I actually asked for and received an antique pair of roller skates because I wanted them more than a new pair of rollerblades(I used them too), and I was into older vintage bicycles instead of modern ones. I also thought rotary phones were cool, though I never actually had one. I loved going through antique stores.
I'm only 22 right now, none of that stuff was nostalgic for me as it was before I was born. I just thought it was cooler and better quality compared to the current stuff that was around at the time. Now stuff is even worse today compared to the 90's, from what I can see anyway. For example, I notice something with the newer laptop my mom has. It runs hotter than mine though they're made by the same company. I can't keep it on my lap as it really gets hot, my older one feels fine. The packaging it came in was cheaper too.
As for video games, I'm mostly into the Genesis which is what I had as a kid. But I'm also into the NES, I only played one for the first time in 2001 so i didn't have any nostalgia for it. I also have an Atari 2600 with some games, but I haven't touched it in ages and I'm not so into it. I don't like systems or games just because they're old, they have to be fun too. I do like other consoles from the 16-bit era, the SNES and Turbografx though I never played those either until more recently. I do like some more current games for the DS and some PC games look interesting, but most current games don't really interest me that much.
